The Daily Grind: Which deceased MMO do you miss the most?

It's official: Flagship Studios' Mythos beta has ceased to be. It's expired and gone to meet its maker. Bereft of life, it rests in peace. It is, in fact, an ex-MMO. Hellgate London subscriptions have halted, and it might soon join Mythos in the great void. There are hopes that they'll be back under a different banner -- or that Hellgate might not close at all -- but if only the worst happens, these two games will certainly be missed by many.
